# RestrictionsManager

`public class RestrictionsManager`
`extends Object` ``

java.lang.Object
↳ | android.content.RestrictionsManager

Provides a mechanism for apps to query restrictions imposed by an entity that manages the user. Apps can also send permission requests to a local or remote device administrator to override default app-specific restrictions or any other operation that needs explicit authorization from the administrator.

Apps can expose a set of restrictions via an XML file specified in the manifest.

If the user has an active Restrictions Provider, dynamic requests can be made in addition to the statically imposed restrictions. Dynamic requests are app-specific and can be expressed via a predefined set of request types.

The RestrictionsManager forwards the dynamic requests to the active Restrictions Provider. The Restrictions Provider can respond back to requests by calling `notifyPermissionResponse(java.lang.String, android.os.PersistableBundle)`, when a response is received from the administrator of the device or user. The response is relayed back to the application via a protected broadcast, `ACTION_PERMISSION_RESPONSE_RECEIVED`.

Static restrictions are specified by an XML file referenced by a meta-data attribute in the manifest. This enables applications as well as any web administration consoles to be able to read the list of available restrictions from the apk.

The syntax of the XML format is as follows:

     <?xml version="1.0" encoding="utf-8"?>
     <restrictions xmlns:android="http://schemas.android.com/apk/res/android" >
         <restriction
             android:key="string"
             android:title="string resource"
             android:restrictionType=["bool" | "string" | "integer"
                                             | "choice" | "multi-select" | "hidden"
                                             | "bundle" | "bundle_array"]
             android:description="string resource"
             android:entries="string-array resource"
             android:entryValues="string-array resource"
             android:defaultValue="reference" >
                 <restriction ... />
                 ...
         </restriction>
         <restriction ... />
         ...
     </restrictions>

The attributes for each restriction depend on the restriction type.

- `key`, `title` and `restrictionType` are mandatory.
- `entries` and `entryValues` are required if `restrictionType` is `choice` or `multi-select`.
- `defaultValue` is optional and its type depends on the `restrictionType`
- `hidden` type must have a `defaultValue` and will not be shown to the administrator. It can be used to pass along data that cannot be modified, such as a version code.
- `description` is meant to describe the restriction in more detail to the administrator controlling the values, if the title is not sufficient.

Only restrictions of type `bundle` and `bundle_array` can have one or multiple nested restriction elements.

In your manifest's `application` section, add the meta-data tag to point to the restrictions XML file as shown below:

     <application ... >
         <meta-data android:name="android.content.APP_RESTRICTIONS"
                       android:resource="@xml/app_restrictions" />
         ...
     </application>

## Constants

### ACTION_PERMISSION_RESPONSE_RECEIVED

    public static final String ACTION_PERMISSION_RESPONSE_RECEIVED

Broadcast intent delivered when a response is received for a permission request. The application should not interrupt the user by coming to the foreground if it isn't currently in the foreground. It can either post a notification informing the user of the response or wait until the next time the user launches the app.

For instance, if the user requested permission to make an in-app purchase, the app can post a notification that the request had been approved or denied.

The broadcast Intent carries the following extra: `EXTRA_RESPONSE_BUNDLE`.

Constant Value: "android.content.action.PERMISSION_RESPONSE_RECEIVED"

### ACTION_REQUEST_LOCAL_APPROVAL

    public static final String ACTION_REQUEST_LOCAL_APPROVAL

Activity intent that is optionally implemented by the Restrictions Provider package to challenge for an administrator PIN or password locally on the device.

The intent must contain `EXTRA_REQUEST_BUNDLE` as an extra and the bundle must contain at least `REQUEST_KEY_MESSAGE` for the activity to display.
